## OpenAI Reiterates GPT-5.6 as Core for Microsoft Copilot 365 Amid Speculation
**REDMOND, WA** – In a move that aims to clarify and potentially quiet recent industry murmurs, OpenAI has underscored that its GPT-5.6 model remains the “preferred model” powering Microsoft Copilot 365. This statement comes amidst persistent “breakup chatter” suggesting a potential loosening of the deep integration between the two tech giants.
While Microsoft continues to invest heavily in its own in-house AI capabilities, including its MAI-1 large language model, the explicit reaffirmation of GPT-5.6’s role highlights the enduring importance of the OpenAI partnership for key Microsoft products. For now, users of Copilot 365 can expect their AI assistant to continue leveraging the advanced capabilities of OpenAI’s latest iterations, reinforcing the current status quo in this pivotal collaboration.
